Multi-band SAR intercomparison study in the Antarctic Peninsula for sea ice and iceberg detection
Synthetic aperture radar (SAR) systems are one of the best resources to gather information in polar environments, but the detection and monitoring of sea ice types and icebergs using them is still a challenge. Limitations using single-frequency images in sea ice characterization are well known, and...
